Bruno Cardoso Lopes 52431f39a3 Reapply r336660: [Modules] Autoload subdirectory modulemaps with specific LangOpts ... Summary: Reproducer and errors: https://bugs.llvm.org/show_bug.cgi?id=37878 lookupModule was falling back to loadSubdirectoryModuleMaps when it couldn't find ModuleName in (proper) search paths. This was causing iteration over all files in the search path subdirectories for example "/usr/include/foobar" in bugzilla case. Users don't expect Clang to load modulemaps in subdirectories implicitly, and also the disk access is not cheap. if (AllowExtraModuleMapSearch) true with ObjC with @import ModuleName.
